본 연구에서는 비용효과적인 배출권거래를 모델화하여 온실가스 저감비용과 거래 이윤측면에서 한계설정이 배출권거래제에 미치는 영향을 분석하였다. 그 결과 한계저감비용곡선이 한 국가의 배출권거래 행태를 결정하는 주요요소이며, 배출권거래시장에참여하여 저감의무량의 일정분을 거래를 통해 의무를 이해하고 잔여량만을 자국의 기술력으로 저감하는 것이 비용효과적임을 확인하였다. 또한 배출권의 구매량을 제한하는 계설정은 배출권의 초과공급으로 거래가격이 낮게 형성되어 거래이윤이 구매측에 편중되었으며, 판매량 제한 또는 구매와판매 양측의 거래량을 제한할 경우는 반대로 배출권의 초과수요로 거래이윤이 판매측에 편중되는 것으로 나타났다. 그리고 거래량의 제한이 없는 경우에 가장 비용효과적인 배출권거래의 행태를 보였으나, 지구온난화에 대한 역사적 책임또는 형평성 문제, Hot air 거래등의 문제로 한계설정을 해야한다면, 구매와 판매량을 모두 제한함으로써 거래당사국들간의 이윤 편중을 완화하는 방안으로 모색해야 한다는 결론을 얻었다.

As observed and experienced in EU ETS, allowance price volatility is one of major concerns in decision making process for $CO_2$ abatement investment. The problem of linearly non-separable profits functions could emerge when one power company holds several power plants with different technology specifications. Under this circumstance, conventional analytical solution for investment option is no longer available, thereby calling for the development of numerical analysis. This paper attempts to develop a Monte-Carlo least squares model to analyze investment options for power companies under emission trading scheme regulations. Stochastic allowance price is considered, and simulation is performed to verify model performance.

온실가스 감축목표의 달성을 위한 정책은 에너지 가격구조의 개선을 통해 국가 경제의 탄소 집약도를 낮추고 에너지 효율을 제고하는 방향으로 추진되어야 할 것이다. 우리나라는 대규모 배출권에 대하여 배출권 거래제를 시행하고 있으므로, 이를 보완하는 차원에서 배출권 거래제의 적용을 받지 않는 배출원에 대하여 탄소세를 부과하는 정책을 추진할 필요가 있다. 온실가스 감축을 위한 규제(탄소세, 배출권 거래제 등)는 기존세제 구조의 왜곡을 해소하거나 교역조건 개선 효과가 클 경우 경제성장에도 긍정적 영향을 미칠 수 있다.

We analyze the learning-by-doing effects of the allowance pricing system on the Korea's emission trading scheme. The price of allowance (Korean Allowance Unit) is influenced differently by internal market factors and economic conditions variables in the first (January 2015 to June 2016 ) and the second commitment year(January 2016 to June 2017). The prices and transaction volumes of complementary credits (KCU and KOC) as well as economic conditions variables (such as call rate, exchange rate, stock price) are statistically significant only for the second commitment year. Thus, the learning-by-doing effect makes the market participation decision on K-ETS market more efficient in the second commitment year, adopting the previous experience and knowledge in the K-ETS market. The factors estimated significantly in both commitment periods include the institutional binary variable for requiring the submission of the emissions verification reports issued both on February and March.

Korea has the fourth highest CO₂ emission among OECD countries in 2018, As of 2019, total greenhouse gas emissions per capita increased by about 98.2% in comparison to 1990. Korea has promised a 37% reduction in greenhouse gas emissions in 2030 from the projected Paris Climate Change Accord. Currently, many countries use the emissions trading system(ETS) for international carbon management. In 2015, ETS has been implemented in Korea, and the importance of calculating CO₂ emissions from construction machinery has increased. So, we require an accurate calculation of the environmental charges through the allocated CERs. Using the CER price and related search keywords, this paper derive about prediction models of CER price and compare and focus on more accurate prediction about CER price. By this method, the budget needed to establish the initial construction process plan can be calculated based on more accurate predicted CER price.

From the Phase II (2018~2020) of K-ETS, the offset credit from 'CDM projects that domestic companies and others have carried out in foreign countries' can be used in the K-ETS. As a result, stakeholders in the K-ETS market are actively developing overseas CDM projects, such as the 'high-efficiency cook stove project'. which can secure a large amount of credits while marginal cost is relatively low. This paper develops the investment decision-making model of offset project for the 'high-efficiency cook stove project' using the real option approach. Under the uncertainty of the emission allowance price, the optimal investment threshold (p^⁎) is derived and sensitivity analysis is conducted. As a result, in the standard scenario (PoA-S), the optimal investment threshold is 29,054won/ton, which is lower than the stock price (p^⁎_spot). However, allocation entities are not only economics in the CDM project, but also CDM risk factors such as non-renewable biomass ratio, cook stove replacement ratio, equity ratio with host country, investment period and submission limitation of emission allowance. In addition, offset project developers will be able to derive the optimal investment threshold for each business stage and use it for economic feasibility checks.

발전부문 배출권 모의거래는 배출권 거래제 도입시 발전부부문에 미치는 영향 분석을 통해 발전부문의 대응전략을 수립하기 위한 목적으로 2008년에 전력거래소가 주관하여 발전5사(남동, 중부, 서부, 동서, 남부)가 주요 참여사로 하여 국내최초로 국내실정에 맞는 배출권 모의거래를 시행하였다. 모의거래에서는 2가지의 시나리오를 설정하였다. 시나리오 I은 최소발전량 발전, 시나리오 II는 총발전운영계획량과 발전실적량을 일치토록하는 전제조건을 설정하였다. 그 결과 시나리오 I에서 모든 참여사는 최소 조건을 충족하도록 발전하는 전략적 행위로 인하여 전력공급지장이 발생하였고, 시나리오 II는 온실가스 배출량이 적은 LNG발전소의 발전량은 증가시키고, 온실가스량이 많은 석탄화력은 증가 운전토록하는 전략적 행위를 취함으로써 발전원가의 상승으로 인하여 전력가격이 상승하는 결과를 초래하였다. 따라서 향후 우리나라에 배출권 거래제 도입될 경우에 대비하여 전력시장과 연계한 배출권 거래제의 다양한 시뮬레이션이 필요하다.

The primary purpose of Renewable Portfolio Standard (RPS) is to facilitate investment in renewable energy technology. Since emission trading program has similar purpose, it is conceivable to attempt to link RPS and emission trading program through interlinked markets. RPS in Korea with single REC and emission allowance markets has particular advantages for constructing linkages between two markets. This paper provides a real option model to examine investment effects of linkage of RPS to the trading program. Emission permit price and REC price are assumed to follow stochastic processes and renewable investment is irreversible. The result shows that linked market provides further incentive for renewable investment by raising managerial flexibility for power companies.

201X년, 환경인증을 획득하지 못하고 친환경 인쇄공정 관리기술도 보유하지 못한 인쇄업체 A사는 더 이상 주문을 받지 못하고 있다. 더욱이 오랜 고객사이던 C사로부터 친환경 인쇄공정 기술을 보유하지 못했기 때문에 더 이상 인쇄물을 발주할 수 없다는 "통보"를 받았다. 또한 탄소배출권을 확보하지 못했기 때문에 이를 구매하기 위한 비용이 증가해 생산비용의 증가로 가격경쟁력이 악화되어 어려움이 가중되고 있다. 이에 비해 서울 근교의 다른 인쇄사인 B사는 계속되는 인쇄물 발주에 응하느라 바쁘다. 귀찮기는 했어도 친환경인쇄 공정기술을 획득한데 이어 환경인증도 일찌감치 받아 놓았기 때문이다. 또한 다른 업체들에 앞서 한발 빠르게 탄소배출권을 충분히 확보해 가격경쟁력에서도 앞서고 있다.

Out of all the possible actions that can be taken to respond to greenhouse gas reduction, including development of greenhouse gas reduction technology, infrastructure, actions to improve energy saving and efficiency, and offset with carbon emission reductions (CERs), this study shall focus on the investment on CERs. This study will take a look at risks involved with investing in CERs such as UN registration refusal risk and CERs price fluctuation, and will design risk management model which shall be verified. The goal of this paper is to provide optimized CERs investment strategies for different types of investors, such as general trading companies seeking for investment opportunities and financial companies with plans for green products development and investment by preparation for carbon market. It is expected that the global competitiveness of domestic financial companies shall be improved by taking actions on carbon market instead of previous passive response to climate change and that Korea, the number two Carbon Emissions supplier and number one derivatives market in terms of volume, shall be able to lead the worldwide carbon market.
